Energy (signal processing)

Relationship to energy in physics

Energy in this context is not, strictly speaking, the same as the conventional notion of energy in physics and the other sciences. The two concepts are, however, closely related, and it is possible to convert from one to the other:

For example, if x(t) represents the potential (in volts) of an electrical signal propagating across a transmission line, then Z would represent the characteristic impedance (in ohms) of the transmission line. The units of measure for the signal energy would appear as volt2·seconds, which is not dimensionally correct for energy in the sense of the physical sciences. After dividing by Z, however, the dimensions of E would become volt2·seconds per ohm, which is equivalent to joules, the SI unit for energy as defined in the physical sciences.

Critical reception

"Energy" received acclaim from music critics with many calling it the best song of the album. Ryan Dombal of Pitchfork gave the song a positive review and named it "Best New Track", stating "The song isn't aimed to any rappers or pop stars, not Kendrick Lamar, Big Sean or Tyga, but the song lines are dangerous."

Synopsis

Energy (Melissa Manchester song)

"Energy" is a song performed by American singer Melissa Manchester, from her 1985 album Mathematics.

Details

The song was arranged by veteran songwriter Greg Mathieson and was released as the second single from the album, following the underperformance of the lead single "Mathematics", MCA hoped to reverse the album's fortune by releasing this Hi-NRG track with an aim for the club market.

Melissa Manchester filmed a videoclip to promote the song, which sees the singer and her band in a sort of industrial-setting stage performing the song.

The single was released on 7" and 12" formats featuring remixes, but it failed to chart either on the Billboard Hot 100 or the dance charts, and failed to chart elsewhere. The b-side to the single was a non-album song, called "So Full Of Yourself", which was co-written by Manchester and Tom Snow and used as the b-side to all 3 singles off the album.

.africa

.Africa is the proposed Internet generic Top-Level Domain (gTLD) for the African and Pan African communities and users wherever they may reside. The .africa gTLD serves as a regional domain for individuals and entities based in and out of Africa.

Status

The .Africa gTLD has not yet been delegated to any organization as registry operator. The .Africa application that was submitted by DotConnectAfrica Trust is now the subject of an unresolved disagreement with ICANN (DCA Trust vs ICANN) following an Independent Review Panel (IRP) Process that was invoked by DCA Trust under ICANN’s accountability mechanism in October 2013. The IRP was administrated by the International Center for Dispute Resolution (ICDR) of the American Arbitration Association (AAA) New York, US.

DCA Trust had passed all the new gTLD applicant evaluation criteria, but before the Initial Evaluation (IE) result was issued, a Governmental Advisory Committee GAC Objection Advice that had been issued in Beijing in April 2013 was later accepted by the ICANN Board in early June 2013 which caused the ICANN Board to instruct ICANN staff that DCA Trust’s .Africa new gTLD application will not be approved. This had caused the non-completion of the evaluation of DCA Trust’s application; which then led DCA Trust to challenge the ICANN Board decision through a series of accountability mechanism.

Background

Africa and De viris illustribus were partially inspired by Petrarch's visit to Rome in 1337. According to Bergin and Wilson (p. ix). It seems very likely that the inspirational vision of the Eternal City must have been the immediate spur to the design of the Africa and probably De viris illustribus as well. After returning from his grand tour, the first sections of Africa were written in the valley of Vaucluse. Petrarch recalls

The fact that he abandoned it early on is not entirely correct since it was far along when he received two invitations (from Rome and from Paris) in September 1340 each asking him to accept the crown as poet laureate. A preliminary form of the poem was completed in time for the laurel coronation April 8, 1341 (Easter Sunday).

Africa (Karl Wolf song)

Africa is the first official single by Lebanese Canadian singer Karl Wolf from his second studio album Bite The Bullet. The album version of the song features rapper/reggae artist Culture. The song is inspired by the worldwide hit "Africa" by Toto and samples music and covers lyrics from the chorus from the original version, providing new lyrics in place of the original's verses.

Music video

Despite the African title of the song, the music video was actually shot off the shore of Dibba, Oman. The music video for "Africa" starts off with Wolf at his secret island resort on his laptop. He gets a call with the ringtone for "Desensitize" (an earlier hit by Karl Wolf featuring Culture). Culture is on the phone informing Wolf that he is on a boat and heading toward shore to meet up with Wolf.

In the next scene, Wolf sees a sexy woman in a bikini on the beach and starts talking to her. Some other scenes in the video also take place at nighttime with Wolf, Culture, and the same sexy woman in a yellow bikini around a fireplace.
